For Agents
Start, monitor, and cancel disk migration jobs on an Azure Stack stamp to rebalance storage shares or evacuate failing hardware.
Use for: I need to migrate tenant disks off a failing storage share on this Azure Stack stamp, List all running disk migration jobs at the eastus location, Cancel disk migration job 12345 because it is causing latency, Check the status of disk migration job abc-def
Not supported: Does not create or attach tenant disks, run snapshots, or manage public Azure managed disks — use for Azure Stack admin-plane disk migration jobs only.
Jentic publishes the only available OpenAPI specification for ComputeDiskAdminManagementClient, keeping it validated and agent-ready. The Admin Compute Disk Management Client manages disk migration jobs on an Azure Stack stamp — used by operators to move tenant disks between storage shares to rebalance capacity or evacuate failing hardware. It exposes 4 endpoints covering listing, getting, creating, and cancelling diskMigrationJobs scoped to a location. It is an admin-plane API, distinct from the tenant-side disk APIs.
Install Jentic One Beta
Connect the ComputeDiskAdminManagementClient to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the ComputeDiskAdminManagementClient, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with ComputeDiskAdminManagementClient API.
Start a disk migration job to move tenant disks from one storage share to another
Monitor the progress of a running disk migration job by migration ID
Cancel a disk migration job that is no longer needed or is causing impact
List all disk migration jobs at a location to audit fabric-side rebalancing activity
Inspect a single migration job's source share, target share, and status for post-incident review
Use Cases
Patterns agents use ComputeDiskAdminManagementClient API for, with concrete tasks.
★ Evacuate disks from a failing storage share
When SMART warnings or capacity pressure hit a storage share, an Azure Stack operator needs to migrate tenant disks off it without disrupting workloads. The Compute Disk Admin Management Client creates a diskMigrationJob with the source and target shares, returns a migration ID, and exposes status polling so the runbook can wait for completion or escalate.
PUT /subscriptions/{subscriptionId}/providers/Microsoft.Compute.Admin/locations/eastus/diskmigrationjobs/{migrationId} with sourceShare=share001 and targetShare=share002, then poll the migration ID until status is Succeeded.
Audit migration activity at a location
Operators need a periodic view of every disk migration job at a location — running, completed, and failed — to feed capacity reports and to detect runaway rebalancing. Listing diskmigrationjobs at the location returns the full set so it can be summarised by status.
GET /subscriptions/{subscriptionId}/providers/Microsoft.Compute.Admin/locations/eastus/diskmigrationjobs and group results by status.
Cancel a runaway migration
If a disk migration is causing tenant impact (latency, IOPS pressure on the target share) the operator must be able to stop it immediately. The Cancel action on a diskMigrationJob terminates the job and returns the disks to a stable state on whichever share they currently sit.
POST /subscriptions/{subscriptionId}/providers/Microsoft.Compute.Admin/locations/eastus/diskmigrationjobs/{migrationId}/Cancel and confirm the migration enters Cancelled state.
Agent-driven storage rebalancing through Jentic
An AI agent integrated through Jentic can monitor share utilisation across an Azure Stack stamp and automatically open disk migration jobs when a share crosses a high-water mark. Jentic's intent search exposes the right diskMigrationJobs operation and the AAD operator token never leaves the vault.
When share001 utilisation exceeds 85%, create a diskMigrationJob to move 100GB of disks to share002 and report the migration ID.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Azure AD operator tokens are stored encrypted in the Jentic vault. Agents receive scoped access tokens tied to the Azure Stack stamp — refresh tokens never enter the agent context.
Intent-based discovery
Agents search by intent (for example 'migrate disks azure stack' or 'cancel disk migration') and Jentic returns the matching diskmigrationjobs operation with its full input schema.
Time to first call
Direct integration: 1-2 days for AAD operator-token plumbing and admin endpoint discovery. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using ComputeDiskAdminManagementClient API through Jentic.
Why is there no official OpenAPI spec for ComputeDiskAdminManagementClient?
Microsoft does not publish a consolidated OpenAPI specification for the Azure Stack Compute Disk Admin API. Jentic generates and maintains this spec so that AI agents and developers can call ComputeDiskAdminManagementClient via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the ComputeDiskAdminManagementClient use?
It uses Azure Active Directory OAuth 2.0 with the implicit flow at https://login.microsoftonline.com/common/oauth2/authorize and the user_impersonation scope. The caller must hold an Azure Stack operator role. Through Jentic the AAD token is held in the encrypted vault.
Can I cancel a running disk migration with this API?
Yes. Issue POST /subscriptions/{subscriptionId}/providers/Microsoft.Compute.Admin/locations/{location}/diskmigrationjobs/{migrationId}/Cancel. The migration transitions to Cancelled and the disks remain on whichever share they currently occupy.
What are the rate limits for the ComputeDiskAdminManagementClient?
Azure Stack admin endpoints inherit Azure Resource Manager subscription-level throttling (typically 12,000 reads and 1,200 writes per hour per subscription). The spec does not declare separate rate-limit headers.
How do I start a disk migration through Jentic?
Search Jentic for 'migrate disks azure stack', load the schema for PUT /subscriptions/{subscriptionId}/providers/Microsoft.Compute.Admin/locations/{location}/diskmigrationjobs/{migrationId}, and execute it with sourceShare and targetShare in the body. Run pip install jentic to get the SDK.
Is the ComputeDiskAdminManagementClient free?
Calling the admin API itself is free; you must hold an Azure Stack operator role. Costs come from running the Azure Stack stamp, not from initiating disk migrations.
